Landslide Hazard Maps. Landslides tend to occur where past landslides have happened. Where records have been kept, landslide inventory maps provide a useful first level view of where the risk is highest. Slope angle, subsurface geology, and rainfall data added to this knowledge base can inform landslide predictions and mitigation priorities.

The PNSN provides accurate and fast information about earthquakes and volcanic activities in the Pacific... Crustal Faults. Shallow earthquakes in Cascadia, with depths no greater than about 35 km, are caused by the rupture of faults within the North American Plate. The sizes of earthquakes are related to how big their ruptures are, and the biggest crustal faults in our region could produce earthquakes with magnitudes as large as, perhaps, M7.5 ...Out of an infinite number of possibilities, 50 simulations of an M9.0 earthquake were run by The M9 Project team. The individual earthquake scenarios had a few important variations between them, that made each earthquake source unique: (1) the hypocenter location (i.e., where the earthquake starts), (2) how far inland the rupture …Surface rupture is an offset of the ground surface when fault rupture extends to the Earth's surface. Any structure built across the fault is at risk of being torn apart as the two sides of the fault slip past each other. Normal- and reverse- (collectively called dip-slip) faulting surface ruptures feature vertical offsets while strike-slip ...The resulting layer of sediment that the turbidity current deposits are called a turbidite.
